US dependency on Oil

I think that the best option for the united states is to lose its dependency gradually over time, and eventually have no dependency what so ever. Of course it would cost a lot of money to work on alternative fuel sources, but it would save billions in the long run. Not only is it not economically beneficial for the US to get oil from the Middle East, but its not safe. If we are dependent on the Middle East for anything, they can control us. We shouldn't have to second guess ourselves when going into a middle eastern country, but instead we not only have to second guess ourselves, we actually don't because our fear of gas prices rising. Really i am wondering is it possible to win a war on terror while we are dependent on oil. Any time we are making progress they could shoot up oil prices. This is a scary thought if you ask me, which is why we need to become fully independent of oil and energy. As for the water situation, it would be devastating if the prices of water went up, because all that it would effect. The article said basically water is used to make everything we have and eat. But I think that water is less important because we aren't dependant on any other nation for our water, so if water prices go up, its not a result of our country trying to defeat terrorism in the middle east. It is just because of a shortage of water. And maybe if the world would stop being so dependant on the oil that the middle east produces, it wouldn't have to use all the water that it is usign now because the demand would be lowered by so much. Even if the US was the only country who became independent, that is still a huge chunk of OPEC's profit.
